Product Summary

A liquid ring vacuum pump is at lower suction pressures and avoiding erosion damage while eliminating pressure booster pumps or scooping tubes in circular operation as well as for simplified external control of the working liquid, an inflow channel is milled into the control disc behind the suction slot on the side facing the impeller, which channel is in communication with a pressurized liquid passage for gap sealing pressurized liquid. The pressurized liquid feed line is connected to a separator or to the machine sump. For improving the efficiency or the liquid output at higher suction pressures, a relief passage is also provided in the control disc above the pressure slot.
The solution of the stated problem of liquid ring vacuum pump for eliminating erosion damage at control discs and impellers by parts of the working liquid and improved inflow conditions at these points with improved efficiency by reduced gap losses in the lower range of the suction pressure for the gas to be pumped is successfully achieved in circular operation without pressure booster pumps or scooping tubes by forming in the control disc, on the side facing the impeller, at least one inflow channel, located between the suction slot and output slot as seen in the direction of rotation of the impeller and below the shaft passage. The inflow channel extends over the region of the impeller hub up to the region of the blade chamber. In addition the sump of the vacuum pump or, if a separator is provided following the outlet in the end bell, i.e., the source of pressured liquid is connected exclusively to the pressurized liquid feed line leading to the pressurized liquid inlet in the control disc.
